An experiment was conducted to assess the effects of dietary 3,5,3'-triiodo-L-thyronine (T₃) at 0, 10, 20, 50, 100 ppm on growth and survival rate in juvenile black seabream held at 27.9±1.1℃ for 50 days. Fish were fed the T₃ experimental diet for 40 days by hand to satiation in 2~4 times per day. After 50 days period, food intake rate (%), feed efficiency (%), survival rate (%), growth of weight and length (specific growth rates), and condition factor were measured.
Food intake rate was inversely related to the dietary T₃ level. But feed efficiency was not changed by T₃ level. T₃ slightly improved survival rate of larvae. Survival rate of larvae from 100 ppm was significantly higher than that of fish from control. Dietary T₃ influenced growth in length and weight. Growth of black seabream fed a diet containing 10 ppm of T₃ was significantly higher than that of fish fed control. However 100 ppm of T₃ induced the inhibition for length and weight growth. The condition factor was inversely related to the dietary T₃ content.
